Introducing the AOC-6843 series, our most recent innovation in cage guide control valves, offering remarkable dynamic stability and expansive Cv value. Engineered for a wide range of heavy-duty applications, this series is exquisitely designed with a pressure-balanced trim, adeptly handling high pressure drops. The AOC-6843L//D/E series elevates control by integrating advanced multi-hole type cages, expertly crafted to mitigate noise and prevent cavitation, ensuring superior performance compared to standard cages in the AOC-6843 series. Notably, all components, aside from the multi-hole cage, are seamlessly interchangeable with those of the standard AOC-6843 series, allowing for versatility and ease of maintenance. For extreme fluid conditions beyond the scope of this series, we recommend opting for the SNT LIMIPHON control type, promising unmatched control and reliability.
